Quantum

Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

Introduction

Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a system are restricted to discrete values (quantization), objects have characteristics of both particles and waves (wave-particle duality), and there are limits to the precision with which quantities can be known (uncertainty principle).

History

The history of quantum mechanics is a fundamental part of the history of modern physics. Quantum mechanics' history, as it interlaces with the history of quantum chemistry, began essentially with a number of different scientific discoveries.

Principles

Quantum mechanics is a significant part of physics. It was developed to explain phenomena that could not be explained by classical physics, such as the behavior of black bodies and the stability of electron orbitals around the nucleus of an atom.

Applications

Quantum mechanics has been successful in explaining a variety of physical phenomena such as the behavior of atoms, nuclei, and subatomic particles. It is also essential in the development of many modern technologies, including lasers, semiconductors, and magnetic resonance imaging.
